Abstract
The invention discloses a kind of J-type bolt production technologies, comprising the following steps: raw material restructuring；Blanking；Chamfering；Thread rolling；It rushes curved；Truncate leg；Surface treatment；Check and accept packaging；In blanking process, raw material cutting length is lengthened, for guaranteeing the short-leg length of J-type bolt；During rushing curved, the part that cutting length lengthens is added on the short-leg of J-type bolt in the case where guarantee J-type bolt long leg length, is formed convenient for short-leg；The present invention lengthens original cutting length, forms convenient for J-type bolt short-leg；Although cutting length is elongated, processing easy to produce is conducive to the production efficiency for improving J-type bolt so that the ratio of briquetting of product improves.
Description
Technical field
The present invention relates to bolt technical fields, and in particular to a kind of J-type bolt production technology.
Background technique
J type bolt is easy to appear problems when production, and reason is that J-type bolt short-leg is too short, it is not easy to add
Work.Preferable effect can not be obtained when using bending machine and the processing of punching machine contoured bottom tooling, when using bending machine, is held
Material spring easily occurs, while J-type bolt J-type position is not round and smooth, it is in irregular shape；When using contoured bottom tooling, it has not been convenient to
Material is taken outward, influences production efficiency.
Summary of the invention
In order to overcome the above technical problems, the present invention provides a kind of J-type bolt production technology, by producing work to J-type bolt
Skill redesigns, and mainly cutting length lengthening is eaten, and fully considers the shortest dimension when molding of J-type bolt short-leg length, then
Cooperate corresponding moulds of industrial equipment to form, reaches the requirement for producing qualified products, effectively improve the qualification rate and production of product
Efficiency.
The technical solution adopted by the present invention to solve the technical problems is: a kind of J-type bolt production technology, including following step
It is rapid: raw material restructuring；Blanking；Chamfering；Thread rolling；It rushes curved；Truncate leg；Surface treatment；Check and accept packaging；In blanking process, raw material
Cutting length lengthens, for guaranteeing the short-leg length of J-type bolt；During rushing curved, in the feelings for guaranteeing the long leg length of J-type bolt
The part that cutting length lengthens is added on the short-leg of J-type bolt under condition, is formed convenient for short-leg.
Further, in blanking process, raw material cutting length lengthens 30mm.
Further, during rushing curved, cutting length is lengthened in the case where guarantee J-type bolt long leg length
30mm is added on the short-leg of J-type bolt.
Further, zinc-plated to J-type bolt progress trivalent chromium in surface treatment process, coating >=5um, 140 hours nothings
Red rust.
The invention has the advantages that being lengthened to original cutting length, formed convenient for J-type bolt short-leg；Although blanking
Length, but processing easy to produce are conducive to the production efficiency for improving J-type bolt so that the ratio of briquetting of product improves.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is production process route figure of the invention.
Fig. 2 is the product schematic diagram of J-type bolt of the present invention.
Specific embodiment
Referring to Fig.1-2, the present embodiment provides a kind of J-type bolt production technologies, comprising the following steps: raw material restructuring；Under
Material；Chamfering；Thread rolling；It rushes curved；Truncate leg；Surface treatment；Check and accept packaging；In blanking process, raw material cutting length lengthens 30mm,
For guaranteeing the short-leg length of J-type bolt；It is in the case where guarantee J-type bolt long leg length that blanking is long during rushing curved
It spends the part 30mm lengthened to be added on the short-leg of J-type bolt, be formed convenient for short-leg；In step 7 surface treatment process, to J-type
Bolt progress trivalent chromium is zinc-plated, and coating >=5um, 140 hours without red rust；The screw thread of thread rolling be coarse thread, 2A grades of accuracy class.
